‘Stay indoors’ warning as killer smog hits Lancashire

Asthma sufferers have been warned to stay indoors until Saturday to avoid toxic smog which has blown into Lancashire from the Continent.

Health experts have advised anyone with respiratory problems to take precautions while the air quality is so poor, especially in towns and cities.

The pollution arrived on Thursday from France and mixed with home-grown smog to leave a potentially lethal cloud hanging over parts of the UK, particularly the North West.

It is expected to remain at a moderate level on Friday and is not due to fully lift until the weekend.

Government specialists said people with lung and heart problems should reduce strenuous physical exertion, particularly outdoors, and particularly if they experience symptoms. People with asthma may need to use their inhaler more often. Older people should also reduce physical exertion.
